Expansion joint



Jan. 12, 1932. w. F. KLEEMAN EXPANSION JOINT Filed June 20, 1927 w!awuemtoz Patented Jan. 12, 1932 UNITED STATES PATENT OFFICE WILLIAM F.KLEEMAN, OF CINCINNATI, OHIO, ASSIGNOR TO THE PHILIP CARE MANUFACTURINGCOMPANY, A CORPORATION OF OHIO EXPANSION- JOINT Application filed June20,

My invention relates to improvement in expansion or contraction jointfillers, particularly'for use in highway or other construction where itis desirable: not only to provide means for-permitting expansion andcontraction for the adjacent construction, frequently concrete blocks,but also to provide means whereby the adjacent construction or blocksmay be interlocked with each other.

My improved expansion joint comprises a body of material, preferably aplastic body containing a suitable filler and a reinforcement, soarranged as toretain the tongue and groove construction under theconditions which it meets in handling and transportation from thefactory to the place of instal lation, and also of such a character thatit will retain the form so that it may be used as a form in the layingof the adjacent blocks, especially of concrete, to give the tongue andgroove form to the adjacent blocks as the concrete sets.

In the drawings, Fig. 1 is a cross section of my expansion jointfi'ller, Fig. 2 is a cross section of the modification, and Figs. 3 and4 are cross sections of modifications.

In the drawings, A is a body of bituminous material; BB are layers ofsaturated felt or similar material. In Fig. 1, A is a layer or sheet ofbituminous saturated felt embedded in the joint between two bodies AA ofasphalt or other bituminous material. In Fig. 2, C0 are two layers ofsimilar bituminous saturated felt arranged intermediate two bodies ofasphalt AA and having between them an adhesive coat A1 of asphalt orother suitable material. The sheet or layers C of bituminous saturatedfelt serve as reinforcements for my improved tongue and groove expansionjoint, and if desired the outer plies BB maybe dispensed with and onlythe intermediate reinforcement C be used. E is a tongue projecting fromone side of the joint and F is a groove preferably in register with thetongue. The bottom of the groove F preferably should be arranged beyondthe vertical line of the opposite side of that portion of the expansionjoint above and below the tongue and groove. In Fig. 3, I provide areinforcement D of metal or similar material.

terial which may be in the form of sheet metal or expanded metal, orforaminous metal which does not extend to the top of the joint. In Fig.4 I have shown a modification in which the felt reinforcement C isarranged between the two bodies of asphalt ma- On the surface ofthismodification, I provide a rough or uneven'surface by plac ing aninadhesive contact with the surface granu'larminerals, such as smallstones, coarse sand or other suitable granular material that will tendto engage with the concrete when it sets and becomes a part of it.

This granular surfacing material may be placed as shown in Fig. 4 on thesides of the asphalt bodies AA or may, if desired, be applied to thefelt sheets BB and held in adhesive contact therewith by asphalt orother suitable material.

Claims:

1. In an expansion joint composed of a. body of bituminous material,means intermediate the surfaces of said body for reenforcing samecomposed of a plurality of layers of bituminous saturated felt separatedfrom, but in adhesive contact with, each other, said joint beingdeformed longitudinally to provide aprojecting tongue on one surface anda corresponding groove on the opposite surface.

An expansion joint having a projecting tongue on one side; and acorresponding groove on the opposite side, said joint composed of a bodyof bituminous material, reenforcing means composed of a plurality ofsheets of bituminous saturated felt in ad.- hesive contact with eachother embedded in said bituminous material so as to provide asubstantial body of bituminous material on each side of thereenforcement throughout the tongue and groove section.

In testimony whereof, I have signed my name to this specification.

WM. F. KLEEMAN.
